>95%, by SDS-PAGE with silver staining, under reducing conditions.
<0.10 EU per 1 μg of the protein by the LAL method.
Measured by its ability to induce IL-11 secretion by Saos‑2 human osteosarcoma cells. Hjertner, O. et al. (1999) Blood 94:3883. The ED50 for this effect is 0.1-0.5 ng/mL. The specific activity of recombinant human HGF is approximately 1.5 x 103 IU/μg, which is calibrated against recombinant human HGF WHO International Standard (NIBSC code: 96/564).
Mouse myeloma cell line, NS0-derived human HGF protein Gln32-Ser728 Manufactured and tested under cGMP guidelines.
Amino acid sequencing of the alpha chain was blocked, suggesting it is consistent with Gln32 Gln32-Arg-Lys-Arg-Arg-Asn-Thr-Ile-His-Glu ( alpha -chain) Val495-Val-Asn-Gly-Ile-Pro-Thr-Arg-Thr-Asn ( beta -chain)
1 μg/lane of GMP-grade Recombinant Human HGF (Catalog # 294-GMP) was resolved with SDS-PAGE under reducing (R) and non-reducing (NR) conditions and visualized by silver staining, showing R bands at 34-37 and 60-64 kDa and NR bands at 76-83 kDa, respectively.
HGF, also known as scatter factor and hepatopoietin A, is a pleiotropic protein in the plasminogen subfamily of S1 peptidases. It is a multidomain molecule that includes an N-terminal PAN/APPLE‑like domain, four Kringle domains, and a serine proteinase-like domain that has no detectable protease activity (1‑5). Human HGF is secreted as an inactive 728 amino acid (aa) single chain propeptide. It is cleaved after the fourth Kringle domain by a serine protease to form bioactive disulfide‑linked HGF with a 60 kDa alpha and 30 kDa beta chain. Alternate splicing generates human HGF isoforms that lack the proteinase‑like domain and different numbers of the Kringle domains. Human HGF shares 91%‑94% aa sequence identity with bovine, canine, feline, mouse, and rat HGF. HGF binds heparan-sulfate proteoglycans and the widely expressed receptor tyrosine kinase, HGF R/c-MET (6, 7). HGF-dependent c-MET activation is implicated in the development of many human cancers (8). HGF regulates epithelial morphogenesis by inducing cell scattering and branching tubulogenesis (9, 10). HGF induces the up‑regulation of integrin alpha 2 beta 1 in epithelial cells by a selective increase in alpha 2 gene transcription (11). This integrin serves as a collagen I receptor, and its blockade disrupts epithelial cell branching tubulogenesis (11, 12). HGF can also alter epithelium morphology by the induction of nectin‑1 alpha ectodomain shedding, an adhesion protein component of adherens junctions (13). In the thyroid, HGF induces the proliferation, motility, and loss of differentiation markers of thyrocytes and inhibits TSH‑stimulated iodine uptake (14). HGF promotes the motility of cardiac stem cells in damaged myocardium (15).
